SPECIFICATION forming part of Letters Patent No. $14,670, dated February 13, 1894. Application fi led October 14, 1893. Serial No. 488.13 0. (Io model-) Tooll-whom it may concern:

Be itknown that I, J osnrrr P. Oneanacitt zen of the United States, residing at Dayton,

in theconntyof Montgomery'and State of Ohio,

.have invented-a certain new and useful Improvement in Cash Registers and Indicators, of which the following is a description, reference being had to theaccompanying drawings,

forming part of thisspecificat-ion.

My invention relates to improvements upon the machine shown and described in Letters Patent No. 464,294, granted Hugo Cook December'l, 1891. Said machine has also been illustrated and described in various subsequent patents and applications of said Cook and-others covering improvements upon and modifications of the machine, so that a de: tailed description of that part of the machine which is old will not be necessary here.

In the accompanying drawings Figure 1 is a perspective view of the complete machine,

' including the base .or drawer-compartment containing the money-drawer, with part of. the casing removed to expose the mechanism within; Fig.2 a vertical cross-section of the machine between the second and third banks ofkeys, looking toward the left of "the ma chine; Fi .3 a vertical cross-section of the machine (without the, drawer-compartment) between the first and second rows of keys,

looking toward the right ot the machine;

Fig. 4 a corresponding view in aplane immediately to the right of the right handrow of keys and looking toward the left of the machine; Fig. 5 a detail view of the gearingconnecting the operating handle and driving Shaft; Fig. 6 a detail view of the locking de vice controlled by the keys; Fig. 7 a, detail vertical section corresponding to Fig. 4, with one of the operating keys partially depressed; and Fig. 8 an enlarged perspective detail of part of one of the detent plates.

The same letters of reference are used to indicate identical parts in allthe figures.

The operating handle A of the machine is (set upon a'short shaftB which is geared by a train of gears C D E F, Fig 5, to a rotary shaft Gextending entirely across the machine and which may be called the driving shaft thereof. The shaft G has interposed in it near its left hand end a crank H,-Fig. 2, to

which is connected the up r rear end of a shaft K. At each complete revolution of the operating handle A the shaft G is given a complete revolution and the shaft K oscillated forward and backward throughout its limit of movement.

The numbered keys L, in this instance four banks or. rows of them each containing nine keys, are mounted radially to the shaft K in segmental gnide-plates M N and are surrounded between said plates by coiled springs 0, Fig. 2, which bear at their-inner ends against the-plate N and at their outer ends against pins P passed through the stems of the keys, thereby pressing the keys outward andryieldingly holding them in normal position'. 1

Loosely mounted upon the=rock-shaft K, one approximately ingline with each of the rows of keys, are four gear-toothed sectors Q which mesh with gear-wheelsR (orsegments thereof) loosely mounted upon ashaft S, while the wheels'R mesh with smaller gears '1. fast upon the 'sides of the numbered indicator wheels U. Pivoted to a pendent extension of each sector Q, at V, is an elbow-shaped latchplate W provided with an open mouth X at itsouter. end and with a recess Y upon its rear side. Fast upon the rock-shaft K are four cam-plates Z, one beside each sector Q, and each cainplate has fast upon its side at its upper end a coupling lug A adapted to o0-opernte with the recess Y in the'latch W.- Each of the keysL is provided near its inner end with a notch B, Figs. 3 and 4, which, when the key is pressed inward, is adapted to be engaged by a beveled detent 0' upon the side of an oscillating detent-plate D'and held in itsinner position against the stress of its spring. The detent-plate' D. is curved concentrically to the shaftKand loosely hung thereon by means of arms E' connected to or formed integral with its opposite ends. A spring F'cOnneoted to thelower one of its arms, Fig. 4, pulls it downward and yieldingly holds it in the normal position shown.

When one of the keys is p'ressed inward its I beveled inner end rides against the beveled surface of the adjacent detent C and lifts the plate D, against the stress of the spring F, until the notch 13 in the key comes opposite the detent, whereupon the spring P will pull the plate D back to normal position and engage the detent with the notch in": the key. The key is thus locked in its inner'position until the plate D is lifted again to releaseit.

The mode of operation of the parts thus far referred to may be briefly described as follows: If one of. the keys L be pressed in. ward and caught and held by its detent, and the operating handle and driving shaft be then given a complete revolution, the cou pling lug A uponthe cam-plate Z will at the. forward oscillation of the rock-shaft'K engfage the recess Y in the latch-plate W and thereby couple the shaft K to the sector Q,-so that during the backward oscillation of said shaft the sector will be carried with it until the outer end of the latch-plate W engages the inner end of the key which has been pressed inward, whereupon the mouth X of the latch-plate will embrace the end of the key, the latch-plate rock upon its pivot V until its recess Y is disengaged from the lug A, and the sector Q be arrested,while the shaft K, plate Z and lug A will move on backward to normal position alone. .When the sectors Q stand in the position shown in the drawings the indicator wheels U stand at zero or initial position, and the adjustment of the parts is such that when the sector Q in its backward movement is arrested by the inner end of any operated key the number upon the indicator which correspondsto the value of such key will have been brought to theindicating point and the registering mechanism (not shown) will have been actuated to add the value of such key to the amount theretofore registered.

It is desirable that means be provided for preventing operation of the machine except when one of the keys has been pressed inward and caughtby its detent-plate, so that the value thereof will be indicated and registered when the handle is tnrn'ed. To that end the Cook patent heretofore referred to illustrated and described a locking device for the operating handle, controlled -by:and cooperating withthe keys in such manner that the normally locked handle would be unlocked by pressing in any one of the keys in either ban k, and would become automatically relocked at the end of its revolution. ,1 have illustrated a similar device in Fig. 6 of the om an 'in drawings.-- ast uphn flieouter end of a rock-shaft G is a lever H whose upturned rear end bears ainst the periphery ofva disk 1 fast upon the shaft s which carries the gear E. The

i k I has one portion of its periphery cut away, forming an ,abrupt shoulder ,at K. The upturned rear end of the lever H norally stands in the path of this shoulder K, so that until the front end of the lever is lifted and its rear. and thrown downward the shaft 5 and gear E, and consequently the opand lift the (bout end of the lever I1 and do 1 press its rear end, thereby carrying the latter out of the path'of the shoulder K upon the disk 1' and unlocking the operating handle. 1

The operation of the machine thus far de f scribed, including the locking mechanism controlled by the keys, is substantially the saino as that shown and described in the Cook patent before referred to, and the first feature of my invention relates to the keys and detent-plate and their co-operatiou witih the locking mechanism. .Uuder the constr ctiou heretofore employed it was possible to press one of the keys inward just far enough to release the operating handle, without pressing it far enough to cause its notch to be caught by the co-operating detent, so that upon releasing the key its spring would throw itoutward to normal position and the revolution of the operating handle would thereupon cause the sector correspondiugto such row of keys to be carried backward by the rock-shaft K to its limit of movement, thereby turning the indicator to indicate nine, the highest amo".-'-**-. that could be iudicatedmnd causing thesam'e amount to be added upon the register, no matter which keyhad been pressed.

- It is the object of this part of myinvention to provide means for locking the partially depressed key from outward movement before it has been pressed far enough to release. the operating handle, and to also automatically lock all of the other. keys in the same row, so that when any key is pressed inward far enough to release the handle it can not be withdrawn 'nor can any other key in the row be operated until, such key has been pressed inward to its full extent and the op crating handle given a complete-revolution, to indicate and register its value, and to lift the detent-plate and release such key. (The detect-plates are all lifted at the end of each operation of the machine, to release the operated keys and, permit their springs to throw them outward to normal position, by-mcaus which is illustrated and described in detail in the Cook patent before referred to andv the beveled surface of the detent C immediately above or in rearof it and thereby moves the detent-plate upward and rearward and this movementof the plate carries the projection I" of the detent which is immediately below or in front of the key into the notch or recess of the key. The key isthns confined between the two adjacent detents, its

projections P of 'the adjacent dotents, the

upward and rearward 'movernent of the detenvplate D' having carried such projections immediately beneath the inner 'ends of such keys. N ow, by the means to be described, the detent-plate Df is caughtand held in the position shown in Fig. 7 as soon as it is moved thereto by the partial depression ,of any key in the row, so that such key cannot be with drawn nor any other key pressed in, and the only thing possible is to fully depress the partially depressed keyand operate the machine to indicate and register its value.

Mounted by elongated slots upon the shaft K and upon a screw stud Q, Figsz3 and 4, is a latch -bar R" provided in itsupper edge near its front end witha notch S in which his the beveled lower end of 8. lug '1" upon the detent-plate D'. A-spring U connected to the rear end of the latch bar R- tends to pull the latter rearward, but the engagement of the lug T with the notch S prevents such movement of the bar.- When any one of the keys is pressed inward to the position shown in Fig. 7, and the detent plate D lifted, its lug '1" will be carried out of the notch S,

' whereupon thesprlug U' will pull the latchbar R rearward and carry the shoulder fornied'by the notch S beneath the lug "l", thereby supporting the detent plate D in the position shown and preventing return of it to normal position. The partially depressed key is therefore held locked, and depression of any of the other keys will be prevented until the latch-bar R is moved forward to its normal position and the detent-plate I) returned to its normal position by its spring F.

(The latch-bar it is moved forward to norenough tounlock the operating handle, so

that the partially depressed key will be locked in its displaced position, as in Fig. 7, before the operating handle is released, and it will therefore be impossibleto so manipulate any one of the keys as to release the operating handle and then'withdraw the key before the handle is revolved. w

Under the construction illustrated in the drawings the notches O' are but, simply in the sides'of the keys L and the'projections .P, upon the detents C are only Wide enough to correspond to the width of the notches, but it will be understood thatby cutting the jnotches .o' the run width (fir-thickness of-the keys it would be unnecessary to makethe detents and their projections of the irregular shape shown and they could be made'of the shape indicated by the section lines in Figs.

'4 and 7, having simply parallel beveled sides and parallel ends. For the purpose of lifting the detentrplate B' and unlocking the operating handle, without depressing any key,-as for instance where it is desired to turn the handle simply for the purposeofopening the cash-drawer to make change 'or otherwise, there is provided a. special key-lever E ,Figs. 1, "3, 4 and 7, which is fast upon a rock-shaft F which has'secured upon it an arm G bearicg against the under side of the lower arm E of the detent-plate D. Whenever the front end of the leverE" is depressed the shaft F will be rocked and the arm G will lift the detent-plate and urilock the operating handle. 'I'he'lever E, shaft F and arm G? are also intended to be used as a key-releasing device, in which event the shaft will be extended entirely across the-ma-. chine and be provided with four of the arms G one beneath each detent-plate D. For such purpose, also, the lever E is extended rearwardly of the shaft F and its rear end is bent upwardly to form a earn 1 adapted to co-operate with a pin J 2 projecting laterally from the side ofthe latch-bar B, Fig. 3. This rearward extension of the lever E could as well be a separate arm fast upon the shaft F, and there would be three other similar arms fast upon said shaft, one beside each latch-bar R and adapted to cooperate with its pin J. New, with the parts in the position shown in Fig.7, or with one of the operating keys fully depressed, if it be desired to release such key-and depress another one before the operating handle is turned, as where the wrong key has been depressed by mistake, the front end of the lever E willhe pressed downward. This will cause all of the (latent-plates D to be lifted, but this alone wouldnot release any partially or wholly depressed keys, for the reason that when the lever E was released the detent-plates D could not return fully to normal position but would be caught upon the latch-bars R, as'in Fig. 7, and the keys held from outward movement by the locking projection P. It is therefore necessary that the latcl1-bars R be moved forward by the depression of the lever E so that the detent-plates can drop into the notches S, and it is for this purpose that the cams I and pins J are employed When the lever'E is depressed the cams I will engage the rear sides of the pins J. and force the bars R forward as the cams pass the pins, but inasmuch as the arms G at this time lift all of the detent-plates the bars R will not be caught and heldin forward position by thelugs T upon the lower ends of such plates.

' When the lever E is released, however, and the cams I move downward to normal position they will ride over the pins J and force the bars R forward again, and. at this time the arms G2 will have permitted the plates'D to have moved downward far enough for their lugs'l" to engage the notches S and hold the bars R in their normal forward positions.

For the purpo e of preventing the simultaneous operation of two or more keys in the same row there is provided a series of pivoted stop-plates H beside each row of keys,

Fig. 3, which plates co-operate with the laterally projecting ends of the pinsP before described. When a single key is pressed in- -ward its pin simply spreads the adjacent plates apart and passes between them, but when it is attempted to press two keys at once their pins become locked upon the iu-- termediate plaie or plates.

The next fea ure of my invention relates to means for preventing operation of the ma- Yf secured in the compartment behind it.

The belt is lifted to release the drawer at each operation of the machine by means of a cam Z"upon the shaft G, Fig. 3, which cam bears upon the rear end of a vertically guided rod A whose lower end is connected to one end of a lever B which passes at its opposite end through a slot in the upper end of the bolt W, Fig. 2. At each revolution of the shaft G the cam Z depresses the red A and rocks the lever B and lifts the bolt W and releases the drawer. Hung upon the central rock-shaft K, Fig. 2, is a three-armed lever C whose upper rear arm projects into proximity to the shaft Gand whose lower rear arm extends down into the drawer-compartmerit. Fast upon the shaft G is a cam D which co-operates with the end of the upper arm of this lever. Vhen the drawer is in its closed position the lower arm of the lever rests upon the rear wall of the drawer and the lever is held in the position shown iu Fig. 2, with its upper arm out of the path of the cam D, but when the drawer is opened and its rear wall withdrawn from the lower arm of the lever the latter will osciilateforward and the tion whenever desired.

It provided with the pins-J, thev rock-shaft upper end ofits upper arm will move into the path of the cam D, so that when the latter ar-- rives at normal position, Fig. 2, it can move no lock secured to the casing or framework, so

that when the plate is thrown downward it will'engage the'forward end of this arm and maintain the lever in its normal position whether the drawer be open or closed. In

this manner the lever maybe thrown and 8e temporarily maintained out'of loekin g opera Having thus fullydescribed my invention, I claim- 1.
